摘要

The friction material plays an important role in ensuring the quality of the brake pads. Friction and wear characteristics of friction material are the decision makers in new formulations of composites materials developed for the brake systems. In this work, it was developed four recipes of frictional materials using coconut fibres reinforcement in aluminium matrix, using powder metallurgy technique. For these new materials developed are presented the physico-mechanical characteristics in accordance with various relevant international standards. These materials for brake pads are tested to determine their tribological behaviour in a standard pin on disc equipment. In this sense, the wear resistance and the evolution of friction coefficient of these composites materials were determined. The comparative study reveals that proposed composites have acceptable level of physic-mechanical and tribological characteristics. The study allows selecting the best formulation of frictional materials for use in manufacturing of brake pads for vehicles.
